To all whom it may concern: Be it known that l, 'lHoMAs ROLAND Won-LASTON, a subject of the Kin of Great Britain, residing at 26Corporation street, Manchester, England, have invented certam new anduseful Improvements in Gas-Producers, of which the following is aspecification.

This invention relates to improvements in apparatus for generatingproducer gas, and of the character set forth and illustrated in thespecification of my prior British Patent No. 1%00 of 1914, in which thefuel bed is annular in form by reason of a central or eccentricallyarranged core or dome wlthln, through which the blast is suitablydirected prior to its introduction to the fuel zone and, in becomi I, 1superheated, abstracts heat from the fuel a lln carrying outthisinvention, l provide or the blast, one or more jets or spraynozzles,

of convenient form, for water or tar liquid, or both, so that spraysofwater or tarmay become vaporized and intimately assoclated with theblast at or about the ,osition at which the same meet, and in t oncourse through the core aforesaid become vaporized or brought to afinely d1v1ded condition or fog, and superheated, prevlous tointroduction to the combustion zone of the producer.

With reference to the accompanying drawings, Figure 1 is a sectionalelevation of the main portion of a gas producer showlng a central hollowcore in connectlon with the grate, and an internal blast pipe asdescribed in the specification of my former patent referred to hereinsaid core bemg provided with liquid supply and atormzmg means arrangedaccordmg to my present invention.

Figs. 2 and 3 show sectional elevations of modifications of theinventlon.

. ith reference to, Fig. 1, a, a, are the walls of the producer which issituated above a water trough b and provided with a fuel grate 0.Through this grate extends a blast pipe at toward the upper end 6 of ahollow core 7" about said blast pipe, and according to my former patentbefore named.

In addition to the means already described, and according to my presentinvention, I provide means for introducing water or tar liquid, or both,in a finely divided or atomized condition, within the passage or dothrough which the blast passes.

In Fig. 1 the 'means consist of a depending pipe it provided with asuitably perforated nozzle it, and so as to operate as an atomizer,through which'pipe water or tar liquid is ejected for the purposestated, In

Fig. 2 a number of de ending pipes It fitted aperture, the two aperturesnot being oppo- I site to each other.

It will be seen that on the -urgence of the water or tar from the pipesh, it will mingle with the blast from the pipe 02 and become vaporizedand superheated. On its passing down the outside of the blast pipe 03'and between it and the core f, further heat is abstracted from the hotzone of the producer as compared with that abstracted w1th the use ofthe blast alone, since by the means described, the degree of saturationof the blast is raised; added to which, when injected tar is used, thelatter is partly converted to fixed gas, v

The combination blast eventually issues from the grate a into thecombustion zone of the producer. With reference to Fig. 2, the passagefor the blast or interior of the core is shown provided with severalspray pipes it and to operate as atomizers, projecting through the tocover of said core, which core is of that c aracter which extends to theupper part of the producer. It is obvious that all the pipes it could besupplied with water for spraying purposes, or could be supplied with tarliquid, or partly the one and partly the other,

ln any case the sprayed or finely divided vapor is capable of morereadily mixing with the ejected contents of the blast ipe d.

With reference to Fig. 3, a sim1 ar kind of core is shown to thatillustrated in Fig. 2,

' but the blast pipe cl does not ehtend so far up the same. Theremainder of the upper part of said core is taken up by a coil is,having perforations 'm inits lower portion through which coil water ortar liquid may be forced or passed so as to emerge near to the outletfor the blast pipe d. The lower portion of said coil referred to, wouldbe provided internally as an atomizer as already described or otherwisebe capable of acting as an atomizer.

I claim In a gas producer with a rate, and in combination, dependingliquif supply and atomizing means within a rigidly mounted hollow coreextending from the grate of said producer, and a blast pipe withextremity in external and op osed to said depending means, within saicore, substantially as herein set forth.

In testimony whereof I have afiixed my signature.

THOMAS ROLAND WOLLASTON.
